1 µL - 2 µL sample. No dilutions. No cuvettes. Less than 5-second measurement.
The NanoDrop™ 2000c Spectrophotometer uses an innovative sample retention system to hold microvolume (1µL -2 µL) samples between two measurement surfaces using the surface tension properties of liquids - no cuvettes needed.
This system allows for path lengths as small a 50 microns so that even very high concentrations of protein can be measured without dilutions. No dilutions mean preparations for sample quantification are easy and cleanup is fast - simply wipe the measurement surfaces with a laboratory wipe.
This video article demonstrates two methods for quantification of microvolume amounts of protein using A280 absorbance readings and the BCA colorimetric assay.
